Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCashEngine shows offers where shoppers decide: the product page, the cart, the cart drawer and the thank-you page. Build a quantity bundle, buy X get Y, a bundle with free gifts, a frequently-bought-together card or a cart rewards bar in a four-step wizard. Discounts are applied at checkout by a Shopify Function, so product prices stay untouched.
Upselly builds real Shopify bundle products. Each bundle shows up as one line at checkout, with native inventory tracking and a genuine discounted price next to the original. There is no widget faking totals in the cart. You can also add frequently bought together offers, BOGO deals, quantity breaks, free gifts and cart goal rewards, and every offer is applied as a real Shopify discount at checkout.
